According to online reports, Echo Protocol, the Bitcoin liquidity re-pledge and revenue layer, said that today its wallet containing 2515.648579 uBTC (currently valued at more than 266 million US dollars) encountered a highly complex supply chain attack and has been maliciously hacked. The team has launched an emergency investigation and will release an incident review report as soon as possible. At present, the mortgage rate of the platform treasury has been reduced to 20%. In order to ensure system security, all cash withdrawal operations will be suspended from midnight EST. Echo Protocol said it is working closely with auditors and security experts to handle the incident and will announce a reward plan later to encourage people familiar with the matter to help track stolen assets.
